Sulfides of Nonmetals, NESOI; Commercial Phosphorus Trisulfide

Spanning arsenic sulfides (2813901000), phosphorus sulfides including commercial phosphorus trisulfide (2813902000), and other nonmetal sulfides (2813905000 and 2813906000), this heading covers a chemically diverse group of inorganic sulfide intermediates. Phosphorus trisulfide is a critical input in the manufacture of safety matches and certain pesticides, while arsenic sulfides find use in glass, pigments, and semiconductor applications. Italy and India lead US supply, with Japan, Germany, and the United Kingdom also among the top source countries.
